The historic peninsula is divided into two districts: Eminonu and Fatih. Eminonu is where you'll find most of the major attractions: Hagia Sophia, Sultanahmet, New Mosque, the Grand Bazaar, the Egyptian Bazaar and others. Closer to Sultanahmet you'll find this to be one of the more touristy areas of town but closer to the water in the streets around the Spice Bazaar you can find more authentic shops, restaurants and sites.
